There's more than one issue in play here. There's the vilification and hate speech done with malice. Freedom of expression is not absolute.The support (solidarity and financial) and sympathy that Folau is garnering on this issue would dispute that. It's clear that people are divided on it, it's not as black and white as 'progressives' would like everybody to believe hence the on-going never-ending furore in the media.
That was the same argument gay marriage proponents used to argue that a plebiscite would cause unnecessary emotional damage on young homosexuals because it would've given those who didn't agree with gay marriage a platform to express their 'bigotry'. Weird that that logic wasn't applied for this incident.
Then there's the ethics of a man with a property portfolio worth millions setting up a fund that pretty much allows him to use the proceeds as he sees fit.
The hypocrisy of him not living up to the love one another as I loved you bit.
And when you say opinion is divided, I'd suggest it's far from and equal division and Folau's reputation in the eyes of those outside the fundies has been damaged irreparably.
